Title: Two-wire remote control and display device
Inventor: TOMITA AKASHI
IPC: H02J13/00
Filed: 1981-03-02
Abstract: PURPOSE:To transfer control information and display information with simple constitution by transmitting the control information according to the phase angle of an AC power line and the display information according to the direction of a current by using the same two-wire circuit. CONSTITUTION:When control information is at a normal position (main line), two inputs to the phase comparator PHC of a subordinate station B are put in phase with each other through the operation of the switches WR1 and WR2 of a master station A, and a control reaction relay WPR is energized. When it is at the opposite position (side line), on the other hand, those two inputs are out of phase and the WPR is released. When display information is transmitted through the main line, a switch S1 is closed and through the operation of a rectifying element D1, a DC current component flowing through a current direction detector KR is positive, so the output contact of the detector KR is placed at the normal position. Therefore, a master station A knows that the display information of the subordinate station B is transmitted through the main line. When the display information is transmitted through the side line, a switch S2 is closed and the output contact of the KR is placed at the opposite position.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To omit an in-phase AC signal feedback circuit, consisting of an operational amplifier and a resistance and to attain the miniaturization and a high degree of integration for a feeder circuit by adding a limiting current generation circuit into a DC signal feedback circuit, which limits the DC to be supplied to a short distance subscriber line down to a level which is lower than the limiting current value. SOLUTION: A and B line voltage detection circuits 102A and 102B output the currents iA and iB, proportional to voltage VA and VB of the subscriber lines A and B to an adder circuit 103. A differential signal elimination circuit 104 calculates a differential AC from the limiting current iTH outputted from a limiting current generation circuit 110 and the currents iA and iB and generates differential signal elimination output currents i104 A and i104 B containing no differential AC to feed them back to the A and B line feeder circuits 101A and 101B respectively. Thus, the high and low impedance characteristics are realized to the differential AC and an in-phase AC respectively. Furthermore, the limiting levels can be set by a single circuit 110 to the feeding currents of both lines A and B.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a correlation synchronizing circuit to generate a synchronization signal to obtain a stable correlation signal, even when the correlation signal is multiplexed in a direct spread spectrum communication system. SOLUTION: A correlation output signal, whose square-sum-square root to be inputted is calculated, is compared with a specified threshold value by a discriminator 1, when output exceeding no threshold value are continuously outputted twice, a signal is transferred in a timing of the output, and the signal is outputted one-time in a spread cycle (a multiplexed block) by a processing part 4. The fact that signals from a processing part 4 are continuously outputted with the same timing several times is confirmed, and synchronization is established by an initial synchronization circuit 2. A pulse is generated with a timing in which the next correlation output is not outputted consecutively twice (once in a multiplexed block), so that the established timing is held by a synchronization counter 3.  The output of the synchronization counter 3 is compared with the output of the processing part 4 by a decision part 5 and correlation synchronization is held by counting up a correct lock counter, when the timing coincides and counting up an erroneous lock counter 6 when no timing coincides.

Filed: 1983-02-28
Abstract: PURPOSE:To prevent positively abnormal temperature rise of a thermal element comprising a thermal head by installing a means to watch heating time of the thermal element and stopping compulsorily head driving when the heating time exceeds the predetermined value. CONSTITUTION:Normally, by each element signal driver transistors Tr1-Trn of each driving member 10 are driven, and thermal elements R1-Rn of a thermal head 12, are heated individually. A comparater CMP compares an electric voltage value basing upon an electric current detecting resistance Rs and a reference electrical potential Vref. generating a comparative output Sgi. A counter circuit 20, while the output Sgi counts a clock signal SCLK on an H-level, campares the result with a set value of setting unit 22b by a comparator 22a. If no abnormal temperature rise occurs in elements R1-Rn, as the output Sgi drops down to an L-level, the SSTP is not generated and supply of electric power is continued. Consequently, at the time of abnormal temperature rise, the H-level continues with generation of the output SSTP stopping supply of power from the power source.

Abstract: PURPOSE:To inform the sound of necessary information relating to a preset time by making the storage of a register, which is made operative to store the time difference between the present time, the measuring time and the preset time at a preset time interval within a preset time period, relate to the sound quantitizing data. CONSTITUTION:A buffer register D introduces and stores any of the time informatino H2 and H1 of the 10 and 1 units and the minute information M2 and M1 of the 10 and 1 units of a register B.
